What are property taxes?
Property taxes are costs charged by your local government, like state, county, municipality, or township. They are based on the “real property” you own, which is your land and any structures on it, like your home. Typically, the more valuable your property is, the more you’ll owe in property taxes.
How do property taxes work?
Property taxes support local government operations and critical infrastructure like roads, water, sewer systems, and schools. They’re determined by local and state governments and typically change each year.
Your home’s value is usually reevaluated each year, in some places it may be every few years, to calculate how much you owe. It’s common for your property tax bill to change from year to year.
How are property values determined?
To calculate property taxes, the county assessor first must determine the market value of your home. They use one or more of the following methods.
- Sales comparison method: The assessor reviews the sales prices of similar homes in your area to value your property, and adjusts based on any renovations and other factors specific to the home.
- Cost method: This method estimates the cost to rebuild your home using current labor and material prices, then adjusts for depreciation.
- Income method: The assessor evaluates how much you could potentially earn from renting the property, factoring in the costs of insurance, taxes, maintenance, and property management.
After determining the home’s market value, the assessor applies an assessment rate to calculate the portion of value that is taxable. This is rate varies by tax jurisdiction.
How are property taxes calculated?
Once the taxable value is determined, the local government deducts any qualifying exemptions and then applies the millage rate (also known as the mill rate or mill levy).
Deduct any qualifying exemptions
Some exemptions can reduce your property tax bill:
Agricultural exemption: Your local government may offer exemptions if you use your home for agricultural purposes.
Homestead exemption: Reduces property takes for homeowners who use the home as their primary residence. A homestead exemption is only available in some states and may have age restrictions.
Homeowners with disabilities exemption: You may qualify for an exemption that reduces or eliminates the property taxes you owe.
Senior citizens exemption: If you’re a senior citizen living on a fixed income, you may qualify for an exemption.
Veterans exemption: Veterans or active duty service members may qualify for a tax reduction, depending on location.
Apply the mill rate
Once any exemptions are applied to the property’s assessed value, the mill rate is used to calculate the property tax.
One mill equals $1 in tax for every $1,000 of assessed value. For example, if a property is assessed at $700,000, a levy of one mill would result in a tax of $700.
Your city, county, and school district have the right to tax the properties within the area. These taxes, often known as levies, add up to calculate the total mill rate for any given property.
When do you pay property taxes?
There are three ways you can pay property taxes – monthly, quarterly, or in full. If you pay monthly, your property taxes will likely be included in your mortgage payments. Your mortgage servicer will set aside the property taxes and pay it will the bill is due.
Your other options are to pay your property taxes quarterly or in full. You’ll likely pay directly to your local tax office. Keep in mind that each year’s taxes are paid the following year.
Effective property tax rates by state
Property taxes vary by area and fluctuate based on local laws and housing market conditions. One way to estimate property taxes is by looking at your state’s effective tax rate.
